The correct answer is (c). The Miyawaki method is a method of forest regeneration that involves planting dense stands of native trees and shrubs. It is well known for its ability to create mini forests in urban areas. The method was developed by Akira Miyawaki, a Japanese botanist, in the 1970s. It has since been used to create forests in over 30 countries around the world.
The Miyawaki method is based on the principle that native trees and shrubs are better adapted to local conditions than non-native species. They are also more likely to form a dense canopy that provides shade and shelter for other plants and animals. The method also involves planting trees and shrubs in close proximity to each other, which helps them to compete more effectively with weeds and other invasive species.
The Miyawaki method has been shown to be effective in creating forests that are more biodiverse and resilient to climate change than forests created using traditional methods. It is also a cost-effective way to create forests, as it requires less land and fewer resources than traditional methods.
(a) Promotion of commercial farming in arid and semi-arid areas: The Miyawaki method is not well known for this. It is a method of forest regeneration, not commercial farming.
(b) Development of gardens using genctically modified flora: The Miyawaki method does not involve the use of genetically modified flora. It is a method of forest regeneration that uses native trees and shrubs.
(d) Harvesting wind energy on coastal areas and on sea surfaces: The Miyawaki method is not well known for this. It is a method of forest regeneration, not wind energy harvesting.
